200A amperage rating paired with a 240V three-pole, four-wire configuration enables direct connection to motor loads and process equipment, delivering clean disconnects and predictable fault interruption. This helps minimize arc flash exposure during servicing and reduces short-circuit risk in line starts, enabling safer, more reliable operation across manufacturing cells and utility feeds. The NEMA 12, NEMA 3R enclosure in painted galvanized steel provides durable protection in dusty and damp environments, extending service life in food and beverage, packaging, and general process facilities. Fuse class provision (Class H) with fusible configuration including a neutral delivers selective coordination and controlled fault isolation, improving protection against nuisance blows and reducing component replacement costs. Enhanced visible blade offers quick status verification during maintenance, boosting uptime and field productivity. The design supports #6-300 kcmil Cu/Al terminations with neutral, simplifying wiring, reducing install time, and enabling future scalability for expanding lines or retrofits. UL Listed and NEC barrier compliance further strengthens safety standards compliance, helping you meet regulatory expectations while lowering risk mitigation costs.

FAQs
DH324NDKV is designed for a four-wire, three-pole installation at 240V. It accepts neutral and provides a fusible path with Class H protection. Plan for #6-300 kcmil copper or aluminum conductors, and ensure enclosure mounting aligns with NEMA 12/3R standards. Verify proper lockout/tagout provisions and clear visibility of the enhanced blade during installation.
The switch supports up to 200A with 240V operation and a three-pole, four-wire configuration. It is suitable for motors and process loads up to 15, 25/15, 60/40 hp ratings depending on service and DC conditions. The device uses Class H fuses and offers neutral functionality to ensure proper coordination and shutdown in motor control centers.
Yes. The unit provides NEC 230.62 (C) compliant barrier protection and is UL Listed, with a NEMA 12/3R enclosure suitable for indoor, dusty, and damp environments. This combination supports code-compliant installation in commercial and industrial facilities and helps ensure safe operation and maintenance access per regulatory standards.
Fusible with neutral allows for proper current return paths and protects against harmful fault currents, while Class H fuses provide fast-acting, high-capacity interruption. This configuration improves selectivity, reduces nuisance tripping, and enhances overall system reliability in equipment like conveyors, pumps, and fans found in process lines.
The enhanced visible blade simplifies status checks during routine inspections, reducing maintenance time. UL Listing and NEC barrier compliance lower compliance risk, while the rugged NEMA 12/3R enclosure and durable galvanized steel construction extend service life in challenging environments. Overall, expect reduced downtime, safer servicing, and lower total cost of ownership over the switch’s life cycle.
